I recently took my 2.5 yo MBA to the apple store for what appeared to be a hard drive issue. Several months ago both the hard drive and the logic board were replaced and a few months before that the battery was replaced (all under apple care). I got a call today telling me that instead of fixing my computer they were going to give me one of the new macbook airs. I got the choice between a 13" with 64 gigs or any of the 11" ones. I asked how much they would charge to upgrade to the 13" with 128 gigs and they ended up saying they wouldn't charge. Has this happened to anyone else? Not to look a gift horse in the mouth but why are they doing this?
